• Mazda CX5 - Commitment to Diesel 11 Feb 2022 (Forum)
  Surprising to see Mazda s commitment to diesel after all the negative comments reported by owners on this site about major problems whilst shortly out of warranty . Lets hope they have finally sorted the DPF issues as the road tests indicate that the extra power from the diesel gives it the performance lacking in the petrol.
• Mazda 3 - The Japanese are back 1 Feb 2019 (Forum)
  Stunning new model now launched AND with a diesel option surprisingly. Would have thought they have had enough grief with their DPF problems ? And with the Skyactive engine having a switchable function on the spark plugs this car is state of the art. But its refreshing to see another example of the renaissance in Japanese stylists following on from the CHR.
• Volkswagen Tiguan - turbo 24 Dec 2015 (Forum)

• 2010 citroen c3 picasso 1.6 diesel 90bhp - how often must timing belt be changed 27 Apr 2013 (Forum)
  does this model have a DPF, how often does the timing belt have to be replaced, what with having a dual mass flywheel, is this a sensible buy.

  The diesel particulate filter light on the dash board has just started tocomes on but there appears to be no DPF. The cat is a one piece unit so what is causing the light to come on. The car has done over 110k Any ideas?
• Ford Kuga (2008 - ) - Kuga sales suspended 19 Jun 2008 (Forum)
  I'm told that Ford have banned the supply of all models, even those that have been paid for and are already at the dealers, due to insuperable problems with the DPF blocking. Any owners come across this?
• 2008 Mazda 6 2.0 Diesel - Losing Power 1yr+, Engine & DPF Light & Rising oil 28 Feb 2011 (Forum)
  I phoned mazda to book it in the following week, but then on a drive home after 100mile round trip the engine light came on, the power loss was far worse (Im guessing limp home mode as I had to put it into 2nd gear to get up a hill on the motorway...) and further towards home the DPF light came on. I got my partner to look at the manual and he said it was ok to get home as long as it doesnt start flashing. Just as we approached our drive way, the DPF light started to flash. They took it in and changed filters (not sure which ones) they also replaced wiring which was apparently causing the DPF & Engine light faults and gave me the car back.
• Vauxhall Astra CDTi 2013 - Vauxhall Astra CDTi frequently running regen 23 Oct 2024 (Forum)
  The garage did say that I'd probably have to do about 400-500 miles to be sure it was just more than the injectors and there is diesel and other crud in the DPF from when it was over injecting, and this also caused the regen to be interrupted on most occasions (pre the injectors being changed) so the DPF wasn't actually getting a good clean out. Does this sound right?
• 2010 vauxhall zafira 1.9 CDTi diesel - ZAFIRA DIESEL 1,9 CDTi GOING INTO LIMP MODE 22 Sep 2023 (Forum)
  Also, would using a diesel additive to clear the DPF help matters? Thanks in advance for any responses.

• Mazda 6 - DCS and ECU Light On, EGR Valve problem, then big 24 Dec 2011 (Forum)
  " If not, the root cause is going to do the same again after I have paid a fortune to get the car working again. I have read on some of the forum about the DPF problem. Could it be the same problem? Shall I remove the DPF or get it regen when the engine is up and running? Could the DPF blockage become too severe and damage the brand new engine again while I tried to get it regen?
• Audi A3 1.9 Tdi e Sport - Used car advice 18 Mar 2018 (Forum)

• Ford Transit Sport 60 Reg - Buying advice required 19 Aug 2014 (Forum)
  Understand that they are fairly heavy on tyres. And there has been cam belt issues with the 2.2 engine. But has the DPF been an issue. Cheers
